ETI on energy saving in buildings

By Dave Elliott

The UK Energy Technologies Institute’s report by Jeff Douglas on Decarbonising Heat for UK Homes notes that ~20% of CO2 emissions are from domestic heating, but says insulation/upgrades won’t cut that enough: ‘the scope for cost effectively reducing the energy demand of existing buildings to the great extent required to meet emissions targets is limited as comprehensive insulation and improvement measures are expensive and intrusive. A several hundred billion pound investment in demand reduction for the entire building stock might deliver less than half of the emissions abatement needed. The most cost effective solutions therefore involve the decarbonisation of the energy supply combined with efficiency improvements that are selectively rather than universally applied, as part of a composite package’.

Prosumer integration

By Dave Elliott

The German Environment Agency (UBA) has produced a comprehensive review of options for removing almost all (95%) greenhouse gas emission by 2050, based on the existing 80% renewables programme for electricity supply, but also looking at all the other sectors – including heating and transport. As I said in my coverage in an earlier post, that is pretty challenging. But it says it can be done. www.umweltbundesamt.de/publikationen/germany-2050-a-greenhouse-gas-neutral-country

Devolving power

By Dave Elliott

‘Distributing Power: A transition to a civic energy future’, a report on research by the EPSRC-funded Realising Transition Pathways Research Consortium of 9 UK universities, argues that up to 50% of electricity demand in the UK could be met by distributed and low carbon sources by 2050. The report assesses the technological feasibility of a move from the current traditional business models of the ‘Big Six’ energy providers to a model where greater ownership is met by devolved governments, municipalities, co-ops and communities. And it looks in details at what types of governance, ownership and control a distributed future would need. (more…)

Capacity Market – the first UK auction

By Dave Elliott

In a fully free-market energy supply system there is no direct commercial incentive for generation companies to ensure that the lights stay on long term, by investing in new and/or backup capacity. Given that some old plants are scheduled for closure and more reliance on sometimes variable renewables is planned, the UK government has stepped in to create a new ‘capacity market’ to try to fill the potential gap in terms of reserve capacity and grid balancing capacity.

Distributed energy: from supply to demand

By Dave Elliott

Energy networks and distributed energy resources in Great Britain”

The context for this IGov paper from Matthew Lockwood at Exeter University, UK, is the desirability of a fundamental shift in the underlying design of the energy system from the supply side to the demand side. It starts by quoting the words of Professor Strbac ‘The whole culture and philosophy of the system is based on a predict-and-provide mentality’. (more…)

World Energy Council- get real

By Dave Elliott

The World Energy Council (WEC) has called for policymakers and industry leaders to ‘get real’ on global energy policy, claiming that the global financial crisis, Fukushima, and the development of unconventional hydrocarbons has changed the context and that, as a consequence, the CO2 targets for 2050 will be missed, unless significant changes and policy frameworks are adopted.

Reaching ‘peak bashing’ of peak oil

by Carey W King

The discussion of the death of peak oil has ramped up along with the increased hydraulic fracturing and horizontal drilling into tight sands and formations across North Dakota and Texas.  In fact, even people that think peak oil will correlate to significant problems for society shy away from the term.  But just as it is becoming more difficult to define what “oil” is in energy databases (it is now popular to report “liquids” that have vastly different life cycles and energy densities), the definition of “peak oil” seems to be in the context of the penholder (or typist).  Since I’m writing this blog, I of course get to define it for myself here, in what is a simple manner:

Peak oil is the concept that someday the rate of oil production for a country, region, or the world will reach a value that will never be exceeded
